Queen Elizabeth Hospital Birmingham says Milne will now work to learn to recognize the sounds she can hear, something she is already experimenting with and enjoying.

"I've heard the birds, running water, even the ping a light switch. When I first did it, I had to go on, off, on, off. I tried it about 10 times because I had to hear it again and again . It's what most people take for granted, switching on the lights. It sounded so beautiful to me," Milne told the BBC.
